` IMPRovi-:M-ENT |N SPRING A-m-'Pls'roL-sf.

Specification forming part of Letters Patent No. 184,698, dated November28, 1876; application filed July 17, 1876.

To all whom it may concern Be it known that I, GEORGE R. CAREY, ofMalden, Middlesex county, Massachusetts, have invented certainImprovements in Air- Pistols, of which the following is a specification:

In this pistol an air-magazine is employed, the outlet of which is atits forward end, and at that point communicates with the rear end of thebarrel, which is received within anextension ot' the frame or stocksurmounting the magazine.

A piston, impelled forward by a powerful spring, is disposed within themagazine in the usual manner, and serves to impel air forward from suchmagazine through the bore of the barrel.

To perform the double function ot' retracting the piston, and of closingthe rear end of the barrel or the small chamber over the magl azine,which constitutes a continuation ofthe bore of the barrel, I employT abent or yokeshaped rod, one arm of which is connected with the plungerand the other operates with the barrel, as hereinafter explained, whilethe bend of the rod serves as a convenient handle, whereby the plungeris easily pulled rearward and cocked against the stress of the spring.v

The manner of combining the trigger and plunger' in this pistol is alsonovel, and will be hereinafter explained.

The drawings accompanying this specification represent, in Figure 1, alongitudinal section, and in Fig. 2 a cross-section, of an airpistolembodying my improvements.

In these drawings, A represents the general frame or stock of the pistolas a straight cylinder, whose interior a constitutes the airmagazine,and in which magazine is disposed a close-fitting plunger, B, im pelledforward by the stress of a powerful spring, C, disposed behind it afterthe manner of many air-pistols now in use.

ln carrying out my improvement, I cast upon the top of the stock A anextension, D, Whose interior b is hollow, Aand constitutes a smallchamber, which communicates with the forward end of the air-magazine bya passage, c, the forward end of the said chamber b being lled by thebarrel E, whose bore d thus constitutes, by means of the said chamber band passage c, the only outlet of the magazine. F represents a bent orC-shaped rod, the lower arm c of which extends through the rear end ofthe magazine a, and is connected with the plunger B in such manner aswhen drawn back to retract such plunger, and to be capable of beingpushed forward without effect upon the latter. The upper arm If of therod F enters the rear end of the chamber b, and serves to close thelatter with an airtightjoint, while the extreme forward end h of sucharm j' is reduced in diameter, and .of such a length as to extendforward to the rear end of the barrel, and serves to push the dart orother projectile into the bore of such barrel. rlhe trigger of thispistol is a bell-crank lever, t', pivoted by a pin, a', within a slot inthe lower part of the stock A, the lower arm j of which constitutes thelinger-pull, w hile the horizontal arm k is formed with a spur or hook,l, to intercept the plunger B when the latter is retracted, and hold itin its cocked` position until released by a pull upon the portion j, theforward end of the plunger being concave or provided with a concavegroove, in order that the hook l shall take firm hold of it.

In the use of this pistol one of the fingers of the right `hand isinserted in the bend m of the rod F, and such rod is pulled backward toits greatest extent, or until its portion h is withdrawn entirely fromthe chamber b and the forward end of the plunger has passed in rear ofandrests against the hook The rod is now turned upon its lower part asan axis until the rear end of the chamber bis unobstructed, and a dartor other projectile inserted in the mouth of such chamber, when the rodis turned back to place and then pushed forward to its extreme limit,the result being that the spur or teat h intercepts and drives forwardthe dart into the rear end of the barrel, and the rear end ot thechamber b is closed against escape of air, it heilig understood that asthe rod is pushed forward its head leaves the plunger and oi'ers noresistance to the sudden advance ofthe latter. The pistol is now loaded,and a pull upon the trigger j releases the plunger B, the latter isdriven suddenly forward by its spring, in its ilight expelling the airin the magazine upward through the passage c, and into and through thebore t the barrel, andexpelling the'dart from the latter.'`

imum of simplicity and low cost. "It ie1 very durable, and is e'eetivein action, and greet power is readily exerted to retract the plunger.

with the magazine a and `barrel F, substantially as` herein shown,whereby onearm of such -shaped roti, in combination rod insertsth'eprojectile and `closes the rear end of the barrel, or the `epproaehthereto,

and the other armoperates the plunger,` the i whole being substantial] yas and for purposes Qt-ated. 4 u
